Abstract:
The field noise tests were performed beside bridges with and without vertical sound barriers in urban rail transit to investigate the structure-borne noise from the bridge-sound barrier system induced by passing trains. The spectral characteristics of structure-borne noise from the box girder-sound barrier system were analyzed by comparing the test results for bridges with and without vertical sound barriers. A vibro-acoustic radiation numerical calculation model of the box girder bridge-sound barrier system was established by using the finite element-boundary element method. The spatial distribution laws of the structure-borne noise from the box girder-sound barrier system were investigated. The effects of train speed and sound barrier height on the structure-borne noise from the box girder-sound barrier system were assessed. Research results show that when a train passes at approximately 93 km·h-1, vertical sound barriers effectively reduce the high-frequency wheel-rail noise but increase the low-frequency structure-borne noise. The effect of structure-borne noise from the sound barriers is mainly concentrated within the low-frequency band below 160 Hz, and the structure-borne noise from the box girder-sound barrier system peaks at approximately 63 Hz. The structure-borne noise from the box girder-sound barrier system decreases with the increasing distance faster in the near field and slower in the far field. The structure-borne noises both above and below the box girder bridge exceed 96 dB, and the structure-borne noise 120 m away from the centerline of the bridge decreases to 72 dB. The sound barrier structure-borne noise significantly influences the girder-side sound field. Compared to the case without sound barriers, the erection of 3.15 m high vertical sound barriers increases the girder-side structure-borne noise by 2-5 dB. The structure-borne noise from box girder-sound barrier system on the girder side increases by more than 7 dB when the speed of the train increases from 93 to 120 km·h-1. The structure-borne noise from the box girder-sound barrier system on the girder side increases by more than 3 dB when the sound barrier height increases from 3.15 to 6.30 m. 1 tab, 12 figs, 30 refs.
